By chance I come across another issue. I was doing aptitude update but I lost internet connection. When I got connectivity again, I tried to do aptitude update again, but only repositories not cached by apt-cacher updated, aptitude stalled on cached repos. After that I noticed that after having stopped the apt-cacher service, there were lots of apt-cacher processes running which wouldn't die with regular killall, so I had to killall -9 them. For the moment I can't provide more information, but I think we could tackle this issues, by a more direct connection, e.g.: jabber if you agree to do so. I'll send you a private e-mail with my account. Regards, -- Raúl Sánchez Siles -Proud Debian user- Linux registered user #416098 signature.asc Description: This is a digitally signed message part.

It includes several restarts with different options and upgrade tries. I hope it is meaningful for you.

I am getting segfaults with libdb4.6 as well. I think this must be a problem with libwww-curl-perl rather than apt-cacher. I have posted a report upstream.

Bug#487789: apt-cacher locks when using checksum and requiring it concurrently.
Package: apt-cacher Version: 1.6.4 Severity: important Hello: When I start 2 aptitude sessions: one for a real system and one for a chroot; and they concurrently run update and/or upgrade I got this message on dmesg. apt-cacher[8117]: segfault at 7f87f70b8e18 ip 7f87f7c37b56 sp 7fff05122448 error 6 in libdb-4.6.so[7f87f7b9d000+145000] This only happens if I enable checksum option in the apt-cacher configuration. When this occurs, downloads eventually stops and those apt-cacher instances hang so that only kill -9 can make them dissappear. I need to run apt-cacher-cleanup -r and then restart apt-cacher service to go on. I started using apt-cacher from around 1.6.0, and I started trying checksum from around 1.6.2.
